HAIR-CLIPPER.

SPECIFICATION forming part of Letters Patent No. 576,301, dated February 2, 1897.

l Application led May 10,1895. Serial No. 548,815. (No model.)

To @ZZ whom t may concern.-

Be it known that I, GEORGE IALCOATES, a citizen of the United States, residing at Vorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Hair-Clippers, of which the following is a specification, reference being had to the accompanying drawings, forming a part of the same, and in which- Figure l represents a top view of a hairclipper embodying my invention. Fig. 2 is a central sectional view on line 2 2, Fig. l. Fig. 3 is a sectional view on line 3 3, Fig. 1. Fig. et is a sectional view of the bottom plate and fixed handle on line 4: 4C, Fig. 1. Fig. 5 is a top view of the cutting-plates, the head having been removed. Fig. 6 is a bottom View of the lower or bottom cutting-plate- Fig. 7 is a sectional view, on a larger scale, of

the bottom cutting-plate, taken on line 7 7, Fig. 6. Fig. 8 represents the under side of a portion of the fixed handle. Fig. 9 is an end view of the clipper, the handles having been removed. Fig. 10 is a transverse sectional view of one of the pressure-bars H', taken on line l0, Figw; and Fig. ll is a top view of one of the pressurebars, showing one of the recesses H2 with the ball H3 removed.

Similar letters refer to similar` parts in the diiferent iigures.

My present invention relates to certain iniprovements in hair-clippers which are provided With stationary and movable cuttingplates and stationary and movable handles, by which the machine is held and operated, and apressure device by which the opposing surfaces of the stationary and movable cuttingeplates are held in contact.

Thepurpose of my invention is to simplify the construction,red uce the cost, and increase the efficiency of the machine; and these objects are accomplished by means of the construction as hereinafter described, and repre sentedin the accompanying drawings.

Referring to the accompanyingdrawings, A denotes the stationary cutting-plate, and A the stationary handle attached thereto.

B denotes the movable cutting-plate, B the vmovable handle, and C the pressure-plate.

The stationary handle A is provided with projecting wings A2 A2, having spurs A3 A3,

Figs. i and S, upon the under side, entering holes ASat A2 in the stationary plate A, which serve to hold the stationary handle from rota` handle to form a bearing at for the movable handle B. The movable handle is held in place by a washer F, resting against the end of the sleeve E, and a nut G, carried by the screw-threaded end of the bolt D, thereby clamping the stationary cuttin g-plate and the stationary and movable handles together.

The movable cutting-plate is pro vided with a longitudinal channel H on its upper surface, in which are placed the pressure-bars H H', held from longitudinal movement by pins H, entering the movable plate B, provided with elongated recesses H2 H2 to receive the balls H3 H3. The recesses H2 H2 are long enough to permit the balls H3 H3 to `roll back and forth as they are moved by the reciprocating movement of the movable cutting-plate- The recesses H2 are `slightly deeper than half the diameter of the balls H3, with their sides curved to correspond with the curvature of the balls H2, so the opening between the opposite sides will be less than the diameter of the balls, in order to prevent the balls from dropping out of the recesses when the head has been removed. The central portion of each recess is enlarged, as at H4, Fig. 11, to admit the balls H3.

`The pressureplate C rests upon the balls IF H3 and is provided With a longitudinal groove C', Fig. 9, along which the balls H3 roll as the movable plate is reciprocated, forming a guideway for the movable plate. The pressure-plate C and stationary cutting-plate A areclamped together by the tightening-bolt land nut l', thereby holding theopposing surfaces of the movable and stationary cuttingplates in contact. l

` J J are studs held in the stationary cuttingplate and entering slots J J in the movable cutting-plate, serving as guides for the mov'- able cutting-plate and also as stops to limit its reciprocatin g motion. The stationary cntting-plate is provided with a recess K on its under side to receive a friction-roll K', which is journaled in the studs K2 K2. One end of the friction-roll K is provided with a gudgeon Ks and the opposite end is provided with a concentric hole K4a to receive a sliding pin K4, forming a gudgeon for the opposite end of the roll, said pin being pressed outward by a spiral spring K5, in order to allow the roll to be inserted between the studs K2 K2.

l am aware that it is not new to attach the stationary handle to the stationary cut-tingplate and to pivot the movable handle upon a boss above the stationary handle, but by means of the sleeve E, formed in a separate piece, I am enabled to attach the several parts together by means of the single bolt D.

I am also aware that it is not new to provide the stationary cutting-plate with a frictionroll, and I do not herein claim such.

That I claim as my invention, and desire to secure by Letters Patent, is-

rlhe combination oi' a stationary cuttingplate provided with holes to receive the spurs of a `stationary handle, a stationary handle provided with wings A2 A2 and spurs A3 A entering the holes in said stationary cuttingplate, said handle having a segmental hole A4, sleeve E having,` one end iitting said seg'- mental hole and provided with a shoulder E bearing against the upper side of said stationary handle, a movable handle journaled on the upper end of said sleeve, a washer resting' upon the upper end of said sleeve, a bolt D passingthrough said sleeve and said stationary cutting-plate and a nut G carried by said bolt, whereby said stationary cutting-plate and said stationary handle are held together and said movable handle is retained in place, substantially as described.

Dated this 5th day of December, 189i.
